Title: Roller bearing and cage therefor
Inventor: BOO OROFU YAKOBUSON
IPC: F16C33/42
Filed: 1989-05-17
Abstract: PURPOSE: To suppress friction to possible minimum without involving a play between rollers and a ring-shaped bearing retainer located between the inner ring and outer ring of the bearing by forming a rubber covering layer partially or over the whole area of the wall surface of an opening to surround the roller. CONSTITUTION: A plurality of rollers 1 are installed between the inner ring 3 and outer ring 5 of a rolling bearing and held by a retainer 7 separated in the circumferential direction. The retainer 7 consists of a ring-shaped member and has openings 9 positioned at certain constant intervals in the circumferential direction. Each opening 9 surrounds respective roller 1 partially, and the wall surface 11 of the opening 9 is lined with a rubber covering layer 13. Owing to this covering layer 13, the rollers 1 have no risk of being damaged, and a lubricant can be held in good performance to allow the bearing to operate with low noise emission, and its lifetime can be prolonged.

Filed: 1977-10-11
Abstract: PURPOSE: To make it possible to obtain the characteristic of distribution of uniform illumination intensity all over the length of a light source by providing reflecting units at either end of the light source formed by arranging many electric lamps.  
     CONSTITUTION: Electric bulb 9... are arranged in line in the lighting device 1 along its longitudinal direction to form a linear light source 15 as a whole. Meanwhile the reflector 20 made of, for example, metal foil is disposed at either end of bottom plate 2 within the body 1 of the device. The inside of the body 1 is wholly painted with black color except the reflectors 20 to turn to light absorbing plane. Therefore it is seen that the light emitted from the light source 15 consists of direct incident light which faces the opening plane 3a and reflecting light reflected on the reflector 20 such that both lights radiate outwardly from the opening plane 3a. On account of the increase of intensity of illumination at either end of the light source 15 by the reflecting light, the distribution of intensity of illumination is shown by the curve A, and almost the identical intensity of illumination can be obtained not only at either end of the light source but also at other parts thereof

Abstract: PURPOSE:To surely form cast billet to the desired shape by calculating deformed degree of the cast billet with the prescribed parameter after passing through bending part and setting mold shape based on the above calculation, so that the final shape of the cast billet substantially becomes right circle. CONSTITUTION:In the case of vertical bending type continuous casting, molten steel 12 in a tundish 11 is supplied in the mold 14 from a nozzle 13 and cooled by the mold 14 to make the cast billet 16. When the cast billet 16 passes through the bending part 2, the cross sectional shape is deformed under the prescribed deformed degree. As the parameter to the deformed degree of the cast billet 6, the equation of flatness ratio D, that is, D=(dA-dB)/d0 is used. In the equation, dA for the max. diameter and dB for the min. diameter of the cas billet 16 after passing through the bending part 2 are used. Based on the D value found by this method, the cross sectional shape of the mold 18 set, so as to become ellipse having major axis (d) and minor axis d0 in the shape before the cast billet 16 reaches to the bending part 2. By this method, the final cross sectional shape of the cast billet 16 can substantially becomes the right circle.

Abstract: PURPOSE:To obtain a device consisting of divided main bodies which are never pressed down even if a load increases by providing a pressure means to the 1st main body side when the 1st and the 2nd main bodies are closed to a release side. CONSTITUTION:The main body 1 is provided with an auxiliary pressure spring 16 which generates pressure by abutting on the 2nd main body 2 right before a hook 7 engages a catcher 9 in addition to spring rods 5 and 6 for elevating the 1st main body 1. While the main bodies 1 and 2 are closed, the main body 1 is applied with force generated by allowing the spring rods 5 and 6 and spring 6 to abut on a fixation device of the main body 2, so the main body 1 is never pressed down even if the load on an original platen 3 increases. Further, the bars 5 and 6 require only force enough for balancing with their weights where the main body 1 is fully open because of the spring 16, so no excessive torsional moment is applied to the main bodies 1 and 2; and the main body 1 never hops up even when the hook 7 is disengaged.
